We really enjoyed our tour with Zack. He was funny and seemed to know his stuff. I wish walking tours had been offered instead of the bus; the bus was a "party" bus, very bachelor party-esque, which was not really our thing. Plus, the breweries were really close together! Several of the other people on the tour were (self-described) drunk by the third stop but they were all happy drunks. We visited Hi-Wire, Burial and Green Man. Overall, a very pleasant way to spend three hours. If I were to go to Asheville again, I would do a self-guided tour. But for a first-timer, the added benefit and knowledge imparted by a guide, was well-worth it.
